This study will assess the efficacy of the modified Attachment and Biobehavioral Catch-Up Intervention, adapted for use with peripartum mothers receiving medication-assisted treatment for opioid use disorder. The investigators expect that mothers who receive the modified Attachment and Biobehavioral Catch-up Intervention will show more nurturing and sensitive parenting and more adaptive physiological regulation than parents who receive a control intervention. The investigators expect that infants whose mothers receive the modified Attachment and Biobehavioral Catch-up will show better outcomes in attachment, behavior, and physiological regulation compared to infants of parents who receive the control intervention.
Peripartum mothers will be randomly assigned to receive the modified ABC intervention or the control intervention (modified DEF). Hypotheses relate to parent and child outcomes associated with the intervention.
Hypothesis 1: Compared to mothers who receive the control intervention, mothers who receive the ABC intervention will show more nurturing and sensitive parenting, enhanced neural activity during parenting-relevant tasks, and more normative patterns of DNA methylation, autonomic nervous system activity, and cortisol production.
Hypothesis 2: Compared to infants of mothers who receive the control intervention, infants of mothers who receive the ABC intervention will show more organized and secure attachment patterns, better behavioral regulation during stressors, more advanced social-emotional development, and more normative patterns of DNA methylation, autonomic nervous system activity, and cortisol production.
Hypothesis 3: Enhanced maternal sensitivity will mediate effects of the ABC intervention on improved infant outcomes.

| Modified Attachment and Biobehavioral Catch-up | Behavioral | Intervention targets include enhancing nurturance and following the child's lead, as well as supporting use of kangaroo care, swaddling, and breastfeeding. |
| Measure | Description | Time Frame |

| Maternal sensitivity | Maternal sensitivity will be coded observationally from maternal interactions with an infant simulator pre-programmed to coo and then cry. Mothers will be coded for sensitivity, nurturance, intrusiveness, detachment, and positive regard, on 5 point scales from 1-Not at all characteristic to 5-Highly characteristic. Higher scores on sensitivity, nurturance, and positive regard represent more positive parenting, whereas higher scores on nurturance and detachment represent less positive parenting. | Pre-intervention (third trimester of gestation or up to one month postpartum) |
| Maternal sensitivity | Maternal sensitivity will be coded observationally from mother-infant play interactions, in which mothers will be given toys and asked to play as they normally would. Mothers will be coded for sensitivity, nurturance, intrusiveness, detachment, and positive regard, on 5 point scales from 1-Not at all characteristic to 5-Highly characteristic. Higher scores on sensitivity, nurturance, and positive regard represent more positive parenting, whereas higher scores on nurturance and detachment represent less positive parenting. | Infant age 3 months |
